Did you examine the postmaster log?  The first few lines should show
what ports it bound to.  For example, on a Linux box I see

2025-06-14 12:48:07.536 EDT [12649] LOG:  starting PostgreSQL 17.5 on x86_=

This won't immediately reveal the problem, I imagine, but it would
help decide where to look.
